Today, the Duchess of Cambridge Kate Middleton visited the iconic Bletchley Park – the site of the UK's World War II codebreakers. The location is known as "Britain's best kept secret," famed for its work with the German Enigma and Lorenz cipher.

Bletchley Park was home to the Government Communications and Cypher School, a code name for Britain's peace-time codebreaking agency. The organization was founded in 1919, and by the 1940′s it was a critical aid to the war effort. Some say that Bletchley Park's decoding efforts shortened the war by 2 years.

For today's military-focused event, Catherine chose to repeat a look by McQueen. The military/nautical inspired shirt and blouse were first worn in 2011 to meet with victims of the Birmingham riots. Today, the outfit seems an appropriate nod to the occasion.

The navy pencil skirt is paired with a white blouse for a classic, vintage look. Catherine paired the ensemble with navy suede courts by Alexander McQueen and a Stuart Weitzman clutch. The Duchess of Cambridge accessorized the navy-and-white look with her sapphire drop earrings

The trip is notably close to Kate's heart – her father's mother, Valerie, worked as a civilian duty officer in the very huts she toured today. Michael Middleton's mother was a member of this heroic codebreaking team.

Bletchley Park recently underwent a year-long restoration, returning the area to its World War II glory. At the location, the Duchess of Cambridge toured the codebreaking huts. Catherine viewed the various interactive displays and demonstrations before meeting the Design and Management Team who worked on the restoration.

Clarence House even tweeted out a photo of Kate's paternal grandmother who looks just like Kate!
The Duchess also met with World War II codebreakers, including a woman who worked with Valerie, Kate's grandmother. These veterans were responsible for decrypting, translating and analyzing military encrypted messages sent to or from the enemy.
